| 23 | # NOTES |
| 24 | # |
| 25 | # I tried to force gmake to use the native shell for simplicity, by |
| 26 | # setting SHELL as below, but this didn't work reliably because of |
| 27 | # various case sensitivity niggles. Specifically, COMSPEC (which is in |
| 28 | # fact usually spelled ComSpec on NT, to make life difficult) typically |
| 29 | # references "cmd.exe" (on NT) when the file is actually called |
| 30 | # "CMD.EXE" on disk for hysterical raisons. As a result, GNU make |
| 31 | # thinks it doesn't exist (unless compiled with a switch to ignore |
| 32 | # case), and so doesn't change which shell it will invoke to execute |
| 33 | # commands. |
| 34 | # |
| 35 | # It would be possible, though very tedious using just gmake facilities, |
| 36 | # to convert the COMSPEC value to uppercase to solve this problem, but |
| 37 | # it isn't worth it. That is partly because, even when using the native |
| 38 | # shell, gmake tends to not be happy with backslashes in command |
| 39 | # strings. The obvious solution is to use forward slashes as much as |
| 40 | # possible, which can be made to work most of the time (putting |
| 41 | # filenames in quotes often helps), but there are still some internal |
| 42 | # cmd.exe commands like `del' and `copy' that won't work with them. |
| 43 | # Although it is possible to convert slashes to backslashes when |
| 44 | # necessary, gmake requires explicitly calling its subst function, which |
| 45 | # nmake does not understand). For this reason, it is simplest to |
| 46 | # mandate that rm and cp be available, so we can use Unix-format file |
| 47 | # names everywhere. (Fortunately both MS and GNU make, and the |
| 48 | # respective compilers, are happy with Unix-format names.) |
| 49 | # |
| 50 | # Since we cannot easily force the choice of a particular shell, we must |
| 51 | # make the effort to cope with whichever shell is being used. |
| 52 | # Fortunately, the only command we need to use that is shell specific is |
| 53 | # the testing of a file's existence for the purpose of working out when |
| 54 | # we are copying files to their original location. That particular |
| 55 | # requirement is abstracted easily enough. |
| 56 | # |
| 57 | # The only other problem area was the change of directory when running |
| 58 | # temacs to dump emacs.exe (where gmake doesn't support cd foo in any |
| 59 | # useful way), but that has been resolved by modifying the Windows |
| 60 | # unexec function slightly to not require the directory change while |
| 61 | # still allowing objects and binaries to be in subdirectories. |
| 62 | |
| 63 | # This doesn't work. |
